Objective To examine and compare the clinical characteristics and treatment of youth with type 2 diabetes (T2D) in two registries: one in Europe and one in the United States. Methods Youth with onset of T2D at 10 to 18 years of age with current age <20 years and an office visit after diabetes duration >1 year were identified in the European (Prospective Diabetes Follow‐up, DPV) and the United States (Pediatric Diabetes Consortium, PDC) databases. Demographic, physical and clinical characteristics and treatment at diagnosis as well as physical characteristics, treatment, laboratory data, and diabetes adverse events at most recent visit were analyzed from both registries. Results At diagnosis, the majority were female and obese; 70% of DPV vs 34% of PDC youth were diagnosed by targeted diabetes testing. PDC youth were younger, 12 vs 13 years ( P < 0.001), had a greater body mass index‐SDS, 3.07 vs 2.74 ( P < 0.001), a higher hemoglobin A1c (HbA1c), 9.9% vs 7.1% ( P < 0.001), were more likely to present in DKA, 7.5% vs 1.3% ( P < 0.001) and more likely to be treated with insulin, 62% vs 32% ( P < 0.001); insulin treatment difference was not significant when adjusted for HbA1c. At follow‐up, DPV youth had shorter diabetes duration, 2.1 vs 3.2 years ( P < 0.001), lower HbA1c, 6.5% vs 7.8% ( P < 0.001), were less likely to be treated with insulin, 36% vs 56%, ( P < 0.001), and were more likely to have dyslipidemia and hypertension than PDC youth. PDC youth had a higher rate of microalbuminuria. Conclusions Both DPV and PDC youth have multiple risks for diabetes complications. Understanding reasons for persistently higher HbA1c in PDC youth requires further study.
